1590s, from French corridor (16c.), from Italian corridore "a gallery," literally "a runner," from correre "to run," from Latin currere (see current (adj.)). Originally of fortifications, meaning "long hallway" is first recorded 1814.

Meaning "to strengthen by evidence, to confirm" is from 1706. Sometimes in early use the word also has its literal Latin sense, especially of medicines. Related: Corroborated; corroborating; corroborative.

late 15c., "size of the body," from Old French cors "body" (see corpse); the meaning "body of a woman's dress, bodice" is from 1818 in fashion plates translated from French; 1843 in a clearly English context. Sense of "a bouquet worn on the bodice" is 1911, American English, apparently from French bouquet de corsage "bouquet of the bodice."

1540s, from Middle French corsaire (15c.), from Provençal cursar, Italian corsaro, from Medieval Latin cursarius "pirate," from Latin cursus "course, a running," from currere "to run" (see current (adj.)).

by 1945, from cortico-, word-forming element from comb. form of Latin cortex "bark of a tree" (see cortex), applied since c. 1890 to various surface structures of plants, animals, or organs + steroid. So called because they are produced in the adrenal cortex. Related: Corticosterone.

1949, coined by its discoverer, Dr. Edward C. Kendall, shortening of chemical name, 17-hydroxy-11 dehydrocorticosterone, ultimately from Latin corticis (genitive of cortex; see cortex). So called because it was obtained from the "cortex" of adrenal glands; originally called Compound E (1936).

1630s, also corvet, from French corvette "small, fast frigate" (15c.), perhaps from Middle Dutch korver "pursuit ship," or Middle Low German korf meaning both a kind of boat and a basket, or from Latin corbita (navis) "slow-sailing ship of burden, grain ship" from corbis "basket" (Gamillscheg is against this). The U.S. sports car was so named September 1952, after the warship, on a suggestion by Myron Scott, employee of Campbell-Ewald, Chevrolet's advertising agency. Italian corvetta, Spanish corbeta are French loan-words.
